2007's Best Children's Hospitals By Specialty

1. The Children's Hospital of Philadelphia: It's home to one of the few pediatric sleep centers in the country accredited by the American Academy of Sleep Medicine. In a recent evaluation, the center was described as "the standard against which all pediatric programs in sleep medicine should be judged."

2. St. Louis Children's Hospital: It is one of two centers in the country participating in all three federal asthma management and research networks; as a result, its rate of unplanned readmissions to the hospital or return to the emergency department because of asthma is very low.

3. Texas Children's Hospital, Houston: The hospital boasts one of the few programs in the country for kids with pulmonary hypertension, (high blood pressure in the artery that supplies the lungs).

4. Columbus Children's Hospital: It created the first device that allows doctors to measure lung function in infants and joined with the Cystic Fibrosis Foundation to manufacture it for other children's hospitals.

5. Children's Healthcare of Atlanta: The hospital has established "Team CF," to increase quality of life for cystic fibrosis patients; 11 studies are underway.
